Note Submitter: ryo at shadowlair dot info ---- Although type-hinting prevents null values from being passed, setting a default null value is not a parse error. However, calling the function with a null parameter, or calling it without the parameter (thus using the default value) will result in a fatal error: <?php function foo(MyClass $object = null) { // this is a valid function definition } $o = new MyClass(); foo($o); foo(null); // fatal error foo(); // fatal error ?>
